Application filed September 25, 1924. Serial No. 789,826.

To all whom it may concern:

Be it known that I, RICHARD Rnnnn, a citizen of the German Republic, residing at Breslau, Germany, have invented certain new and useful Improvements in Roofs for Buildings, of which the. following is a specification.

This invention relates to a roofing of carton pierre for buildings of any kind by which a plane root surface possessing the required capability of expansion and facility of graveling is obtained, an absolute tightness of the joints is ensnred and a dropping of the adhesive'substance through the joints 1 is absolutely prevented even at the greatest heat. The characteristic features of the invention reside in a roof in which main strips of roofing material are laid on the roof in;one single layer'from the ridge to 0 the eaves and in which narrow strips of roofing material are arranged over and.

underthe main strips at the side edges thereof and are connected at their lower ends with a transverse eaves strip extending along the eaves or edge of the roof. The edges of the strips of oarton-pierre are fixed by means of nails driven into the roof boarding through the narrow under lining strips. In the improved roofing the nailing points are covered'by the covering strips so that the joints are absolutely tight against filtration 'of water although a single layer of eaftonpierre is used while hitherto, in order to obtain a water-tight rooting, two layers of r carton-pierre had to be used. 'As the same water-tightness is now obtained with one single layer of cartonpierre the cost of a roof of this type is reduced by 40%.

The improved roofing is shown in the accompanying drawing in- Fig. 1 is a perspective view. Fig. 2 is a section on line 152-?) of Fig. '1. On the eaves of the roof hoarding it a strip 2, of carton-pierre is laid, the lower edge 3 of which is bent down to project over the loweredge of the roof hoarding.

vFroni the ridge to'the eaves narrow lining strips 4% of carton-pierre are placed at dis tances apart which correspond with the width of the main strips of carton-pierre, the, lower edges 5 of these lining strips it. resting upon the transverse strip 2 of cartonpierre. The main strips 6 of carton-pierre are iaid on the roof boarding from the ridge to the eaves so that the joints 7 rest upon the lining strips 4:. The main strips 6.. are fixed in positrim on the root boarding by means of nails 10 which are driven in through the edges of the main strips 6 and through the lining strips 4. O n the joints 7 covering strips 9 of carton-pierre are laid from the ridge to the caves and stuck onto the main strip 6 by means of tar. The lower edges 8 of the main strips 6 and of the covering strips 9"project over the lower ends of the lining strips 4 so that these lower edges 8 rest directly upon the transverse strip 2. The entire surface of the root is plane so that the gravel" 12 can be put on without difficulty. The tar which serves to stick the covering strips on the main stripof carton-pierre is designated in Fig. 2 by the numeralll.

l. A roof of the class described, comprising in combination a transverse eaves strip of roofing material extending along the edge the same at the eaves strip, and covering strips of roofing material arranged upon the main strips at the side'edges thereof.

2. A roof of the class described, comprising'in combination, a transverse eaves strip extending along the eaves or edge of the roof and having its outer edge bent downwardly over the edge of the roof, narrow lining strips arranged at intervals on the roofand having their lower ends overlapping and resting upon the transverse eaves strip, main strips of roofingrnaterial extending from the eaves strip and having their side edgesin abetting relation and arrangednpon'the narrow lining strips and extending beyond the same at the eaves strip and covering strips of roofing material arranged upon the adjacent side edges of the main strips and also extending beyond the narrow joint strips at the said eaves strip.
